Decoding data in new radio ultra-reliable low latency communications with multiple transmission points

ABSTRACT

Described is a technology to reduce the interference between two or more transmit receive (Tx/Rx) points (TRPs) and improve the reliability for New Radio ultra reliable low latency communication (NR URLLC) applications. The technology operates in one aspect at a network node, and in another aspect at a user equipment. If a network device decides to use packet duplication, the network device can indicate duplication to the user equipment. The network device can send duplicate copies, e.g., via two different antenna panels, or can send one copy and coordinate with another network device (e.g., another cell) to send the other copy. When the user equipment receives the copies, the user equipment combines the data, e.g., via soft combining or concatenation into combined data, and decodes the combined data. Weights, such as corresponding to channel quality from each transmit source, can be used as factors in the combining of the data.

TECHNICAL FIELD

The subject application is related to wireless communication systems, and, for example, to scheduling data in wireless communication systems for New Radio ultra reliable low latency communication (NR URLLC) systems in which multiple transmission points are present.

BACKGROUND

In NR URLLC, reliability of the packets is significant. For example, if a first transmit receive (Tx/Rx) point (TRP) is transmitting a packet for URLLC, and a second TRP transmits another packet for URLLC/eMBB (URLLC/enhanced mobile broadband), then the second TRP transmission causes interference to the first transmission. In this case the reliability of the URLLC transmission is reduced.

DETAILED DESCRIPTION

Various aspects described herein are directed towards a technology to reduce the interference between two or more transmit receive (Tx/Rx) points (TRPs) and improve the reliability for New Radio ultra reliable low latency communication (NR URLLC) applications. The described technology operates in one aspect at a network node, and in another aspect at a user equipment (UE) for transmitting and receiving data for URLLC applications.

To this end, in one or more implementations, the network (a network device) checks whether the user equipment is capable of receiving URLLC transmissions (based on UE category or capability) and decides whether to duplicate the packets from two TRPs (assuming the TRPs are co-located). If the network device decides to use packet duplication, the network device decides whether or not to indicate duplication to the user equipment to indicate duplication to the user equipment. Note that the two TRPs can use the same resources or different resources. Similarly, the network can use different ports from the two TRPs.

In one embodiment, the network device will indicate to the UE that the packets are duplicated based on a scheduling decision. For example, if both the TRPs use the same code rate for packet transmission to the same user equipment, then the network indicates to the user equipment that the current transmission from the TRPs is duplicated.

FIG. 1 illustrates an example wireless communication system 100 in accordance with various aspects and embodiments of the subject technology. In one or more embodiments, the system 100 can comprise one or more user equipments, e.g., UEs 102(1)-102(n).

In various embodiments, the system 100 is or comprises a wireless communication network serviced by one or more wireless communication network providers. In example embodiments, a UE 102 can be communicatively coupled to the wireless communication network via a network device 104 (e.g., network node). The network device 104 can communicate with the user equipment (UE), thus providing connectivity between the UE and the wider cellular network.

In example implementations, each UE such as the UE 102(1) is able to send and/or receive communication data via a wireless link to the network device 104. The dashed arrow lines from the network device 104 to the UE 102 represent downlink (DL) communications and the solid arrow lines from the UE 102 to the network device 104 represents uplink (UL) communications.

The system 100 can further include one or more communication service provider networks 106 that facilitate providing wireless communication services to various UEs, including UES 102(1)-102(n), via the network device 104 and/or various additional network devices (not shown) included in the one or more communication service provider networks 106. The one or more communication service provider networks 106 can include various types of disparate networks, including but not limited to: cellular networks, femto networks, picocell networks, microcell networks, internet protocol (IP) networks Wi-Fi service networks, broadband service network, enterprise networks, cloud based networks, and the like. For example, in at least one implementation, system 100 can be or include a large scale wireless communication network that spans various geographic areas. According to this implementation, the one or more communication service provider networks 106 can be or include the wireless communication network and/or various additional devices and components of the wireless communication network (e.g., additional network devices and cell, additional UEs, network server devices, etc.).

The network device 104 can be connected to the one or more communication service provider networks 106 via one or more backhaul links 108. For example, the one or more backhaul links 108 can comprise wired link components, such as a T1/E1 phone line, a digital subscriber line (DSL) (e.g., either synchronous or asynchronous), an asymmetric DSL (ADSL), an optical fiber backbone, a coaxial cable, and the like. The one or more backhaul links 108 can also include wireless link components, such as but not limited to, line-of-sight (LOS) or non-LOS links which can include terrestrial air-interfaces or deep space links (e.g., satellite communication links for navigation).

The wireless communication system 100 can employ various cellular systems, technologies, and modulation schemes to facilitate wireless radio communications between devices (e.g., a UE 102 and the network device 104). While example embodiments might be described for 5G new radio (NR) systems, the embodiments can be applicable to any radio access technology (RAT) or multi-RAT system where the UE operates using multiple carriers e.g. LTE FDD/TDD, GSM/GERAN, CDMA2000 etc. For example, the system 100 can operate in accordance with global system for mobile communications (GSM), universal mobile telecommunications service (UMTS), long term evolution (LTE), LTE frequency division duplexing (LTE FDD, LTE time division duplexing (TDD), high speed packet access (HSPA), code division multiple access (CDMA), wideband CDMA (WCMDA), CDMA2000, time division multiple access (TDMA), frequency division multiple access (FDMA), multi-carrier code division multiple access (MC-CDMA), single-carrier code division multiple access (SC-CDMA), single-carrier FDMA (SC-FDMA), orthogonal frequency division multiplexing (OFDM), discrete Fourier transform spread OFDM (DFT-spread OFDM) single carrier FDMA (SC-FDMA), Filter bank based multi-carrier (FBMC), zero tail DFT-spread-OFDM (ZT DFT-s-OFDM), generalized frequency division multiplexing (GFDM), fixed mobile convergence (FMC), universal fixed mobile convergence (UFMC), unique word OFDM (UW-OFDM), unique word DFT-spread OFDM (UW DFT-Spread-OFDM), cyclic prefix OFDM CP-OFDM, resource-block-filtered OFDM, Wi Fi, WLAN, WiMax, and the like. However, various features and functionalities of system 100 are particularly described wherein the devices (e.g., the UEs 102 and the network device 104) of system 100 are configured to communicate wireless signals using one or more multi carrier modulation schemes, wherein data symbols can be transmitted simultaneously over multiple frequency subcarriers (e.g., OFDM, CP-OFDM, DFT-spread OFDM, UFMC, FMBC, etc.). The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g. interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception. Note that some embodiments are also applicable for Multi RAB (radio bearers) on some carriers (that is data plus speech is simultaneously scheduled).

In various embodiments, the system 100 can be configured to provide and employ 5G wireless networking features and functionalities. With 5G networks that may use waveforms that split the bandwidth into several sub-bands, different types of services can be accommodated in different sub-bands with the most suitable waveform and numerology, leading to improved spectrum utilization for 5G networks. Notwithstanding, in the mmWave spectrum, the millimeter waves have shorter wavelengths relative to other communications waves, whereby mmWave signals can experience severe path loss, penetration loss, and fading. However, the shorter wavelength at mmWave frequencies also allows more antennas to be packed in the same physical dimension, which allows for large-scale spatial multiplexing and highly directional beamforming.

Performance can be improved if both the transmitter and the receiver are equipped with multiple antennas. Multi-antenna techniques can significantly increase the data rates and reliability of a wireless communication system. The use of multiple input multiple output (MIMO) techniques, which was introduced in the third-generation partnership project (3GPP) and has been in use (including with LTE), is a multi-antenna technique that can improve the spectral efficiency of transmissions, thereby significantly boosting the overall data carrying capacity of wireless systems. The use of multiple-input multiple-output (MIMO) techniques can improve mmWave communications; MIMO can be used for achieving diversity gain, spatial multiplexing gain and beamforming gain.

Note that using multi-antennas does not always mean that MIMO is being used. For example, a configuration can have two downlink antennas, and these two antennas can be used in various ways. In addition to using the antennas in a 2×2 MIMO scheme, the two antennas can also be used in a diversity configuration rather than MIMO configuration. Even with multiple antennas, a particular scheme might only use one of the antennas (e.g., LTE specification's transmission mode 1, which uses a single transmission antenna and a single receive antenna). Or, only one antenna can be used, with various different multiplexing, precoding methods etc.

The MIMO technique uses a commonly known notation (M×N) to represent MIMO configuration in terms number of transmit (M) and receive antennas (N) on one end of the transmission system. The common MIMO configurations used for various technologies are: (2×1), (1×2), (2×2), (4×2), (8×2) and (2×4), (4×4), (8×4). The configurations represented by (2×1) and (1×2) are special cases of MIMO known as transmit diversity (or spatial diversity) and receive diversity. In addition to transmit diversity (or spatial diversity) and receive diversity, other techniques such as spatial multiplexing (comprising both open-loop and closed-loop), beamforming, and codebook-based precoding can also be used to address issues such as efficiency, interference, and range.

Another concept is that of the rank of the transmission. In multiple antenna techniques, the incoming data can be split to be transmitted through multiple antennas, wherein each data stream processed and transmitted through an antenna is referred to as a transmission layer. The number of transmission layers is typically the number of transmit antennas. The data can be split into several parallel streams, where each stream contains different information. In another type, the incoming data is duplicated and each antenna transmits the same information. The term spatial layer refers to a data stream that includes information not included at the other layers. The rank of the transmission is equal to the number of spatial layers in an LTE spatial multiplexing transmission, that is, equals the number of different transmission layers transmitted in parallel. Even though the information in each layer may be manipulated in different ways by mathematical operations, when the operations do not change the information transmitted, a transmitter can be referred to as operating as a rank-1 transmitter. In a multi-antenna transmitter, different pieces of information are transmitted in parallel simultaneously in up to four different layers; a transmitter transmitting different information in parallel using four layers operates as a rank-4 transmitter.

In the example of FIG. 1, as described herein, for data channel transmissions, a user equipment (e.g., 102(1)) receives information 110 as to transmission of two duplicate copies of a transport block/data packet from two different transmission sources/TRPs, e.g., two different antenna panels or two different transmission points, each transmission source corresponding to a different cell. Note that if not notified, the user equipment will individually decode each transport block instance and treat the duplicate transport blocks as interfering. Instead, by being notified that the transport blocks are intended to comprise the same data, the duplicated transport blocks can be combined (e.g., soft combined or concatenated as described herein) before decoding, with the combined data decoded once.

FIG. 2 is an example embodiment in which two transmission points correspond to two network devices 204 and 205 corresponding to separate (e.g., adjacent) cells by which a user equipment 202(1) can receive downlink data and transmit uplink data. The network device 204 can communicate with the network device 208 via the core network 206, including, for example to coordinate scheduling of a multiple (duplicate) transmission to the user equipment. The duplicated transport block transmissions are represented in FIG. 2 via URLLC data instances/copies represented by the blocks labeled 208(1) and 208(2).

FIG. 3 is an example embodiment in which two transmission points correspond to two different antenna panels of a network device 304 by which a user equipment 302(1) can receive downlink data and transmit uplink data. The duplicated transport block transmissions are represented in FIG. 3 via URLLC data instances/copies represented by the blocks labeled 308(1) and 308(2).

In general, NR needs to satisfy various services, including eMBB, which is mainly for high broadband applications where the data rate is the main criteria; URLLC, which is mainly for ultra-reliable communications where the packet error rate of 10⁻⁵ is specified with less delay; and mMTC, which is mainly for connecting machine type of communications, where the number of devices is a main criteria.

A typical message sequence for downlink data transfer in 5G systems (called transmission scheme 1) uses pilot or reference signals, from which the UE computes the channel estimates and then computes the parameters needed for CSI (channel state information) reporting. A CSI report comprises, for example, a channel quality indicator (CQI), preceding matrix index (PMI), rank information (RI), and so on

The CSI report is sent to the gNodeB via a feedback channel either on a periodic basis or on-demand-based CSI, i.e., aperiodic CSI reporting. The gNodeB scheduler uses this information in choosing the parameters for scheduling of this particular UE. The gNodeB sends the scheduling parameters to the UE in the (physical) downlink control channel called PDCCH. After that actual data transfer takes place from gNodeB to the UE.

The uplink control channel carries information about HARQ-ACK (hybrid automatic repeat request acknowledgement) information corresponding to the downlink data transmission, and channel state information.

With respect to a coding chain for PDSCH, FIG. 4 shows the transmission side of a MIMO communication system with Nt transmit antennas. There are up to 2 transport blocks, e.g., TB1 and TB2, where the number of transport blocks is equal to one when the number of layers is less than or equal to 4. If the number of layers is more than 4, then 2 transport blocks are transmitted. The CRC bits are added to each transport block and passed to the channel encoder, e.g., blocks 441 and 442, which also represent scrambling. Low density parity check codes (LDPC) is the FEC (forward error correction) for NR. The channel encoder adds parity bits to protect the data. After encoding the data stream is scrambled with user-specific scrambling. Then the stream is passed through an interleaver and modulator (blocks 443 and 444). The interleaver size is adaptively controlled by puncturing to increase the data rate. The adaptation is done by using the information from the feedback channel, for example channel state information sent by the receiver. The interleaved data is passed through a symbol mapper (modulator). The symbol mapper is controlled by an adaptive controller 446. After the modulator, the streams are passed through a layer mapper 448 and a precoder 450. The resultant symbols are mapped (blocks 453 and 454) to the resources elements in the time-frequency grid of OFDM. The resultant streams are then passed through IFFT block (blocks 455 and 456). Note that the IFFT block is needed necessary for some communication systems that implement OFDMA as the access technology (e.g., 5G, LTE/LTE-A); in other systems it can be different, and is dependent on the multiple access system. The encoded stream is then transmitted through the respective antenna.

With respect to code block segmentation in NR, as generally represented in FIG. 5, for data transmission, the transport block is 560 encoded using LDPC code. In one step of the physical-layer processing, a 24-bit CRC 562 is calculated for and appended to each transport block. The CRC allows for receiver-side detection of errors in the decoded transport block. The corresponding error indication can, for example, be used by the downlink hybrid-ARQ protocol as a trigger for requesting retransmissions. If the transport block, including the transport-block CRC, exceeds the maximum code-block size (8448 for base graph 2 and 3840 for Base graph 2), code-block segmentation is applied before the LDPC coding. Code-block segmentation implies that the transport block is segmented into smaller code blocks, the sizes of which should match the set of code-block sizes supported by the LDPC coder.

In the case of a single code block when no segmentation is needed, no additional code-block CRC is applied; code-block segmentation is only applied to large transport blocks for which the relative extra overhead due to the additional transport block CRC is small. Information about the transport-block size is provided to the terminal as part of the scheduling assignment transmitted on the PDCCH control channel. Based on this information, the terminal can determine the code-block size and number of code blocks. The terminal receiver can thus, based on the information provided in the scheduling assignment, straightforwardly undo or assemble the code-block segmentation and recover the decoded transport blocks.

With respect to redundancy version, note that once the information bits are segmented and encoded using LDPC code (either base graph 1 or 2), they need to be rate matched for the transmission. NR uses a circular buffer for rate matching each code block. As an example, the standard defines 4 redundancy versions as shown in FIG. 6. The starting positions of each redundancy version is shown in the following Table:

k₀ rv_(id) Base graph 1 Base graph 2 0 0 0 1 $\left\lfloor \frac{17N_{cb}}{66Z_{c}} \right\rfloor\; Z_{c}$ $\left\lfloor \frac{13N_{cb}}{50Z_{c}} \right\rfloor\; Z_{c}$ 2 $\left\lfloor \frac{33N_{cb}}{66Z_{c}} \right\rfloor\; Z_{c}$ $\left\lfloor \frac{25N_{cb}}{50Z_{c}} \right\rfloor\; Z_{c}$ 3 $\left\lfloor \frac{56N_{cb}}{66Z_{c}} \right\rfloor\; Z_{c}$ $\left\lfloor \frac{43N_{cb}}{50Z_{c}} \right\rfloor\; Z_{c}$

In NR, for each transmission, the network needs to inform to the UE which redundancy version it is currently scheduling. This is communicated via the downlink control channel for PDSCH transmission and downlink control channel (grant channel) for uplink data transmission.

Note that all the versions of LDPC codes designed for 5G wireless communications are not self-decodable, where self decodability generally means, for example, if redundancy version is RV0 for one or all re-transmissions, and if the decoder is able to decode the transport block, then it is referred to as a self-decodable redundancy version. Empirical simulations find that redundancy version 0 (RV0) is self-decodable for any code rate and modulation scheme, redundancy version 1 (RV1) is self-decodable low code rates up to 0.45 and any modulation schemes, redundancy version 2 (RV2) is self-decodable low code rates up to 0.5 and any modulation schemes, and redundancy version 3 (RV3) is self-decodable for any code rate and any modulation scheme.

Turning to aspects related to multiple TRP (transmission/reception or Tx/Rx Point) transmission, FIG. 7 shows a message sequence chart between a gNodeB (gNB1) and a UE 702 with multiple TRPs for downlink data transfer in 5G systems. In general, the same sequence procedure as described above is repeated for the second TRP (gNB2). However, if the TRPs are co-located, then then the scheduling can be optimized by using a single DCI or multiple DCIs.

The technology described herein is generally directed towards using two (or possibly more than two) TRPs to improve the reliability in URLLC applications. In one aspect, at the network node, operations can comprise:

-   -   Obtaining information about the UE capability for URLLC and the         packet application     -   Decide about duplicating the packets from both the TRPs by         coordinating the scheduler     -   Decide to indicate to the UE about duplication if the packets         are to be duplicated     -   Indicate to the UE about duplication of the packets     -   Transmitting the data to the UE

In one aspect, at the UE, operations can comprise:

-   -   Obtaining information about the duplication of the packets from         both the TRPs     -   Determine the RV and HARQ process from the DCI     -   Decide whether to soft combine the data from the two TRPs or use         concatenation based on RV and HARQ of the individual         transmission     -   Decode the data     -   Transmit, to the network node, HARQ-ACK information.

FIGS. 8A and 8B shows typical scenarios with multiple TRP transmission sources 882 and 883 or 886 and 887 to a user equipment (UE) 802 for URLLC applications. The received signal at the UE 802 is given by:

r=H ^(A) P ₁ x ₁ ^(A) +H ^(B) P ₂ x ₂ ^(B) +n

In one or more implementations, the network checks whether the UE 802 is capable of receiving URLLC transmissions (UE category or capability) and decides whether to duplicate the packets from both of the TRPs (assuming they are co-located). Once it decides to use packet duplication, the network has to decide whether to indicate duplication to the UE. Note that, the two TRPs can use the same resources or different resources. Similarly, the network can use different ports from the two TRPs.

In one embodiment, the network indicates to the UE 802 that the packets are duplicated based on the scheduling decision. For example, if both the TRPs use the same code rate for packet transmission to the same UE, then the network indicates to the UE 802 that the current transmission from the TRPs is duplicated.

Once the UE receives the DCI, the UE determines the contents of the DCI, namely MCS (modulation coding scheme), RV and the indication from the TRP about duplication. If the code rate is same, and the RV is same from both the TRPs, then the UE will soft combine the coded bits (before the FEC decoder) thereby improving the performance of system. Note that soft combining refers to one or more techniques, e.g., two identical data packets are combined to improve the decoding probability, in the case of two TRPS, via spatial incremental redundancy.

In another embodiment, the UE checks the DCI and determines the RV and the indication from the TRP about duplication. If the RV is different from the two TRPS, the UE concatenates the soft bits and use one FEC decoder (similar to the HARQ soft combining in traditional systems). However in this case the soft combining is in the spatial domain rather time domain. Hence significant gains can be obtained by using this approach, thereby improving the reliability.

Note that the network can indicate that packets are duplicated by either explicit signaling (e.g., 1 bit) or by implicit signaling in either of the downlink control channels or by using a single downlink control channel.

Turning to another aspect, soft combining of the packets can be based on the channel quality corresponding to the transmission sources. For example, a first weight can be associated with the first signal-to-noise ratio of a first transmission source, and a second weight can be associated with the second signal-to-noise ratio of a second transmission source. Soft combining can factor in the weights, so that the packet received via the better of the two signals has more weight in the combined data to be decoded.

One or more example aspects are represented in FIG. 9, and can correspond to a user equipment device comprising a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations and/or components. Example operations comprise operation 902, which represents receiving information indicating that the user equipment device is to receive a first copy of a packet from a first transmit source and second copy of a packet from a second transmit source. Operation 904 represents receiving the first copy of the packet from the first transmit source. Operation 906 represents receiving the second copy of a packet from the second transmit source. Operation 908 represents processing the first copy of the packet and the second copy of the packet into combined data. Operation 910 represents decoding the combined data.

Processing the first copy of the packet and the second copy of the packet into the combined data can comprise soft combining the first copy of the packet and the second copy of the packet into the combined data. Processing the first copy of the packet and the second copy of the packet into the combined data can comprise concatenating the first copy of the packet and the second copy of the packet into the combined data.

Further operations can comprise, determining a first weight based on first channel quality information associated with the first transmit source, determining a second weight based on second channel quality information associated with the second transmit source, and wherein the processing the first copy of the packet and the second copy of the packet into the combined data comprises soft combining first data from the first copy of the packet, based on the first weight, with second data of the second copy of the packet, based on the second weight, into the combined data.

The processing can comprise performing a data combination operation; further operations can comprise determining the data combination operation to perform to obtain the combined data, comprising evaluating a first redundancy version and first hybrid automatic repeat request information associated with a first copy of the packet, and evaluating a second redundancy version and second hybrid automatic repeat request information associated with a second copy of the packet, to determine whether the data combination operation comprises a soft combine operation or a concatenation operation.

The processing can comprise evaluating a first redundancy version associated with a first copy of the data, evaluating a second redundancy version associated with a second copy of the data, and in response to the first redundancy version being determined to match the second redundancy packet, performing a data combination operation by soft combining the first copy of the data with the second copy of the packet to obtain the combined data.

The processing can comprise evaluating a first redundancy version associated with a first copy of the data, evaluating a second redundancy version associated with a second copy of the data, and in response to the first redundancy version being determined to be different from the second redundancy version, performing a data combination operation by concatenating the first copy of the data with the second copy of the data to obtain the combined data.

One or more aspects, such as those implemented in example operations of a method, are shown in FIG. 10 in accordance with various aspects and embodiments of the subject disclosure. Operation 1002 represents indicating, by a network device comprising a processor to a user equipment, that multiple copies of a packet are to be transmitted to the user equipment from multiple transmit sources. Operation 1004 represents transmitting, by the network device as a first transmit source of the multiple transmit sources, a first copy of the packet.

Transmitting the first copy of the packet can comprise transmitting an ultra-reliable low-latency communication transport block data transmission.

The network device can comprise a first antenna panel as the first transmit source and a second antenna panel as a second transmit source; transmitting the first copy of the packet can occur via the first antenna panel; aspects can comprise transmitting, by the network device via the second antenna panel as a second transmit source, a second copy of the packet.

Aspects can comprise coordinating, by the network device, scheduling of the transmitting the first copy of the packet with a second transmission of a second copy of the packet. The network device can comprise a first transmit source comprising a first transmit point corresponding to a first cell; coordinating the scheduling of the second copy of the packet can comprise scheduling the second transmission via a second transmit source comprising a second transmit point corresponding to a second cell.

One or more aspects, such as implemented in a machine-readable storage medium, comprising executable instructions that, when executed by a processor of a network device of a wireless communication system, facilitate performance of operations, are represented in FIG. 11. Example operations comprise operation 1102, which represents receiving an indication that the user equipment is to receive multiple copies of a packet from multiple transmit sources. Operation 1104 represents receiving the multiple copies of the packets from the multiple transmit sources. Operation 1106 represents performing a data combination operation to obtain combined data, based on data received in the multiple copies of the packet, for a decoding of the combined data.

Further operations can comprise decoding the combined data.

Performing the data combination operation to obtain the combined data can comprise soft combining the multiple copies of the packets into the combined data. Performing the data combination operation to obtain the combined data can comprise concatenating the multiple copies of the packets into the combined data.

Further operations can comprise, evaluating a first redundancy version and first hybrid automatic repeat request information associated with a first copy of the packet, and in response to the first redundancy version being determined to match the second redundancy packet, performing the data combination operation can comprise soft combining the first copy of the data with the second copy of the packet to obtain the combined data, and in response to the first redundancy version being determined to not match from the second redundancy version, performing the data combination operation can comprise concatenating the first copy of the data with the second copy of the data to obtain the combined data.

The multiple transmit sources can comprise a first transmit source and a second transmit source; further operations can comprise determining a first weight based on first channel quality information associated with the first transmit source, and determining a second weight based on second channel quality information associated with the second transmit source; performing the data combination operation can comprise soft combining first data from the first copy of the packet, based on the first weight, with second data of the second copy of the packet, based on the second weight, into the combined data.

Determining the data combination operation to perform to obtain the combined data can comprise evaluating a first redundancy version and first hybrid automatic repeat request information associated with a first copy of the data, and evaluating a second redundancy version and second hybrid automatic repeat request information associated with a second copy of the data, to determine whether the data combination operation comprises a soft combine operation or a concatenation operation.

The multiple transmit sources can comprise a first transmit source and a second transmit source; further operations can comprise determining a first weight based on first channel quality information associated with the first transmit source, and determining a second weight based on second channel quality information associated with the second transmit source; performing the data combination operation can comprise using the first weight and the second weight as factors to obtain the combined data.

As can be seen, there is described a technology that facilitates improved reliability for data channels. Benefits include reducing the power for transmitting the data, using a reduced number of resources for data channels as the number of retransmissions is reduced, and improving a user experience, as the reliability of data transmission is improved and the latency is reduced. These are particularly useful in URLLC communications.
